Ok... But 450 nm, in general, are many? Or to be good?
anyway, I had a look at the map ORI.
your speech: "Look at the absolute values, not percentages.....if you ask 450 nm from the pedal to the limiter, you have to set it to that value if no did not maintain the required torque "
does not seem to actually corresponding to what you say. I'll definitely be layman on the subject but I saw on the map "required torque in standard conditions" that would be one of the maps pedal , to, for example, 100,10% of 2000 rpm there are 390,5 nm while in the map "torque limiter maximum" there are 370 nm, then less than the request from the pedal and let's talk about the map made in alpha...probably I don't understand well the maps, however, I would appreciate more clarity ;-)
thanks a lot
In the expectation of a reply I tried to edit as suggeritomi hoping you understand.
I changed just to test a single map pedal that ecm titanium called "torque request during standard conditions" and I adjusted the torque limiter.
I have taken account of nm and not a percentage. I would like to understand now if the logic of reasoning and variation of the map is correct and also if so how it could go well or is it too much push.
Consequently, if it is ok to proceed in the change equal to the other maps pedal that ecm titanium called the "required torque during the acceleration", "the required torque to the functionality Sports A and Sports B". I had read that these maps need to be changed all the same.
I also changed the two map that ecm calls "limiter, smoke - threshold lambda upper and lower". These honestly I've changed by copying them from a map that I found myself in my date base.I hope you are right.
thanks a lot for the patience

We await suggestions :-)
Hello, given that I am an inexperienced user and in phase of study as I think of you, take what I say with the necessary precautions. Having said that in all the maps that I have seen the GOLD of mother Alpha, map the pedal always has the most torque limiter as you have rightly already noticed as well you, then I think the logic is that the pedal should always ask for a little more torque than the rev limiter. For example, if I want to 4000 rpm 400Nm of torque septum this value in the torque limiter and the pedal, for example setterò 405, and then always something more, because if I did the opposite, i.e. the pedal asks for 395 Nm, and the limiter 400 does not actually limit anything because the value required by the pedal is already below the limit.
I hope I was clear.
I also add that in the set values of the torque limiter according to me you should take into account how much fuel you want to inject it, because then in a subsequent step, the control unit converts the torque request in the amount of fuel to be injected by means of a special map. And if this map is not touched on the last break point is set in 80mm3.
I try to make an example (numbers taken at random, just as an example) to see if I can explain myself. Let's say that at 4000 rpm set limiter to 400Nm, with the value in the map the pedal to 405Nm. The map conversion torque/diesel me as a value 83,70mm3, then when the ecu will look for the time to inject the amount of fuel that will for the 1600 bar of pressure, and 80mm3 a value of 863 microseconds. But how much will it be for 83,70mm3? Boh the ecu does not know why the last break point, precisely, is 80, and there was another calculated column will take the last available value and that is always 863 microseconds, but doing so at the end it will eventually inject a maximum of 80mm3 because the time of that opening. The solutions are 2, or change the break point of the map injection times and calcolarseli for more than 80mm3 or in the first phase of the study simply want to inject a maximum of 80mm3 (assuming, of course, that then this is possible because it is said that there is enough air to burn it all). In this case, the making of calculations starting from the map conversion torque/diesel in back (I have built excel spreadsheets for these calculations) I get for example that if the septum to 4000 rpm with a value of 386,1 Nm I get as the amount of diesel just 80mm3, and always for example at 3500 rpm 395,4 Nm I will always 80mm3. What I mean is that without changing the map injection times this will also limiter, and then in fact I do not allow you to overcome the 80mm3 so you do not overdo it with the values in the torque limiter, why not get no appreciable advantage. As I said before, put at 4,000 rpm 400Nm or 386,1 in the end I think it will produce the same effect.
according to me for a map calculated and informed indication of the torque limiter, you can also "unlock" in a way that does not interfere. We think the other maps, including the lim iq to make the correct limitations, if calculated well
What address are the limiters for diesel?
I've seen the map is not too bad..but there are some things to review..
in the meantime, begin to put ori the table, dtc cheparte from the address 1c88da
then you touched on the map calculation of torque of internal friction that is 1cba82 is a map that serves to the ecu for its calculations, especially when the car is cold at the moment, no need to change it..
you skipped the torque limiter that is located immediately after the map 1cbcba edit it...
the axis of the torque limiter main return it ori as you did serves no purpose..
you missed the limiters of the first and second gear and I don't understand the meaning since they are set at 260 and 290 nm, if they don't unlock even if the pedal request 450nm around and from the lim couple to act 420nm about 100mm3 of fuel you won't see them ever in first and second gear arrange them..
maps lambda I is usually imposed on all the lambda-1, or of 14.5 for afr if sfucchiano a little raised where it is needed and if I need more diesel the down where you need it here you need to log the car and fsarti two calculations to figure out how to edit them correctly.
map 1e1592 return it ori.
pressure turbo you got up to 135 points I do not really like the same thing pre the rail pressure got up in a fixed manner and is also of little use in the interpolation of the titanium and by increases from 3 to 6-7%.
maps vgt ok if you need more thrust down by another 2-3% more..
the map in the game you missed..
as well as all of the limiters for diesel but no one has been modified, but very little..
the map injection times are you game to change from 250bar to rail and from 5mm3 iq that is in the machine stop virtually parts to 400bar, and the 10-15mm3 also you get to change the curves injection related to 1800bar not need a visa that does not arrive at that pressure there would be to upgrade the axis of the press in the times, to adapt it eriscalarlo more so as time but for now we'll leave that alone..
A rider does not create queues even in the car...
a automoblista create queues even on a motorcycle...
first of all, thanks very much.
so..I changed the map 1CBCBA and I increased all of the 4%..it is okay or what should I put?
the axis of the torque limiter main what would it be? is the one address that goes to 1CBD00 to 1CBD28 and that is increased 3%?
the maps lmabda I changed...right?
the maps limiters for diesel, are a to the address that it goes 1CC052 to 1CC0AC, and the other by 1CC116 to 1CC214?? if ok, in this case how can I change it?Increase in all the curves, for example, of 4%?
about the swirl I have to clear to zero the map that goes from 1E79E2a 1E7B2E?
I have also given a bit of advance on the map that ecm titanium called "phase injection - Inienzione main base map 1,2,3,4, and 5"? going well for you?
also, I made ritocchini at the time of injection
I hope I have understood something and that I'm moving in the right way!
In the expectation of a pious soul, I could not resist and I made other changes...type limiters of diesel (I hope they are right) ,lambda,swirl, injection phase etc etc
you could give it a okkiata and tell me what is good and not?
I have loaded and I have to say that the car goes better with the other map.No smoke!
Regarding the clutch slip , if it sank to 2000 a little slide...if accellero gradually the car is fine and you get a good progression.
then I should probably lower the torque between 2000 and 3000 rpm right? or if I drive without sinking, I could leave it as is?
The other thing I noticed...after 3000 rpm the car pulls but I would like the tachometer to go up faster,and more fluid, I don't know how to explain it. In this case the parameters are modified to have a faster rise of the rpm from 3000 onwards?
thanks a lot
